A Korean Startup Lestur, business AI transformation partner, has successfully secured Pre-Series A investment. With this funding, the company aims to enhance its AI operations management capabilities and accelerate its expansion into the enterprise AI market. This investment round was co-led by existing investor Stonebridge Ventures and new investor KB Investment.

Letsur has successfully supported over 100 enterprises in AI adoption across various industries, leveraging its advanced AI operations management platform, Staix. This platform, an upgraded and reengineered version of the previous LAMP system, is designed to enable organizations dealing with large-scale data and complex processes to manage and sustain AI without the need for specialized developers. Staix ensures stable AI operations even under high traffic conditions, significantly lowering the technical and financial barriers companies face when implementing and maintaining AI solutions.

A key competitive advantage of Letsur lies in its long-term operational support and continuous performance enhancement model rather than offering one-time solutions. Many enterprises struggle with AI implementation due to workforce shortages and escalating maintenance costs. However, Letsur’s AI operations management service allows businesses to cut costs by over 70% while maintaining stable AI service operations without requiring in-house AI specialists. Additionally, through its ‘Able Campus’ program, Letsur enhances organizations’ AI utilization capabilities, enabling continuous service updates to ensure access to the latest AI advancements.

Thanks to this strategic approach, Letsur achieved over 200% year-over-year revenue growth and secured 150 cumulative customers last year. The company has attracted a diverse clientele, ranging from startups to large corporations, achieving a remarkable customer retention rate of over 70%. Notably, in the first quarter of this year alone, Letsur has already surpassed its total revenue from the previous year in contracted deals.

Recognizing Letsur’s rapid growth, Stonebridge Ventures reinforced its commitment by making a follow-on investment, highlighting the company’s technological expertise and proven business model. Similarly, KB Investment was drawn to Letsur’s high customer retention rate and the expanding AI operations management market, leading them to participate in this round. Both investors identified Letsur’s key strengths as its effective AI operations management services, strong customer loyalty, well-established long-term collaboration model, and potential for business expansion through AI expertise.

Leveraging this latest investment, Letsur plans to further solidify its position as a leading AI operations management company. The newly acquired capital will be allocated toward expanding customer support teams, strengthening AI service integration, and hiring additional AI consultants. Particularly in Q2 of this year, Letsur aims to scale up its service offerings and significantly increase AI consultant recruitment, broadening its reach into industries such as finance, manufacturing, and retail.

Shin Sang-rok, Principal at Stonebridge Ventures, stated, “As AI technology rapidly advances, the primary challenge enterprises face is shifting from mere adoption to continuous operation and management. Letsur has demonstrated strong technological capabilities and an impressive customer retention rate among leading domestic enterprises, which solidified our decision to invest further.”

Kyu-hyun Shim, CEO of Letsur, remarked, “The most significant challenge for enterprises implementing AI is ensuring ongoing operations and sustained performance. Letsur is committed to providing a comprehensive solution covering everything from AI deployment to operations and training, establishing itself as a reliable and long-term AI lifecycle partner for businesses.”
